  • Enables Naveena Steel to enter growing market for regional infrastructure projects
  • Production capacity is 270,000 metric tons of rebars per year
  • Smaller diameters are rolled in multi-slit mode to increase productivity
  • Direct rolling of hot billets will reduce fuel cost

Primetals Technologies has received an order from Naveena Steel Mills (Private) Limited (Naveena Steel) to supply a continuous billet casting machine and a bar rolling mill for a new mini mill in Port Qasim, Karachi. The billet caster will be supplied by Concast (India) Ltd., a Primetals Technologies group company. The new mill will enable Naveena Steel to the enter the growing market for regional infrastructure projects.

The mini mill  will produce around 270,000 metric tons of reinforcing steel (rebars) per annum with diameters ranging from 8 to 40 millimeters. Diameters up to 12 millimeters will be rolled in multi-slit mode to improve productivity. As a special feature of the new plant, billets will be directly charged in hot condition to the rolling mill, which will provide significant energy savings. An inline induction furnace placed before the first rolling stand will serve to equalize the billet temperature, providing the seamless integration of the caster and rolling processes. Commissioning is scheduled to start in the second quarter of 2019.

Naveena Steel was founded in 2018. It is part of the family-owned Naveena Group. Established in 1971, it is active in the textile, wind-power and real-estate areas. Current production sites are in Karachi, Lahore, Pakistan and Dubai, UAE. In the context of the implementation of the China Pakistan Economic Corridor project in Pakistan, infrastructure development is expected to increase steel demand. For this reason, Naveena Steel is planning to set up facilities for melting, casting and rolling with a total capacity of 270,000 metric tons per year. The mini mill will be located in proximity to Port Qasim, Karachi, resulting in cost effective import of basic raw materials like scrap.

The continuous casting machine consists of two strands, with provisions made to add a third strand in the future. The caster has a curved tube mold, and is a multiple-radius machine, with a basic radius of 6 meters and a second radius of 11 meters. Maximum casting speed is 4 meters per minute. Concast (India) is responsible for designing, engineering and manufacturing of ladle support, tundish and tundish support, mold and oscillator, straightener segments, secondary cooling, dummy bar system as well as pusher and cooling bed. Concast (India) will also supply the basic automation (level 1) and HMI system. The caster produces the starting material for the bar rolling mill, 9 meter long billets of low and medium carbon steels, with a square cross-sections of 130 x 130 millimeters.

The billets will be hot charged to the rolling mill, which will produce rebars with diameters ranging from 8 to 40 millimeters. In order to increase the productivity of the plant, bars with diameters between 10 and 12 millimeters will be rolled in two-slit mode, and those with diameter 8 millimeters in three-slit mode.  The rolling line will consist of a furnace discharging area, a 6-stand roughing mill in VHVHHV arrangement, a 6-stand intermediate train in HVHVHV arrangement, and a 4-stand finishing train in HHHH arrangement. The type of all rolling stands will be Red Ring Series 5. The maximum rolling rate is 45 tons per hour, the maximum finishing rolling speed amounts to 12 meters per second.

An inline PQS quenching system gives the bars a tempered martensitic case and a ferritic-pearlitic core, enabling Naveena Steel to obtain the YTS UTS A% values required by applicable standards (like DIN, ASTM, and Indian standards). The downstream hot dividing shear is equipped with an optimization system to maximize the utilization of the cooling bed and guarantee the pre-set number of commercial-length bar layers per bundle. The cooling bed is 54 meters long and 8 meters wide, with the possibility to extend it in future to a total length of 66 meters. A cold static dividing shear, handles the final cutting of the rolled bars. This is followed by automatic bundling, binding, weighing and dispatching of bundles. The scope of supply also includes fluid systems and operational parts, such as stand-by Red Ring stands, rolling rolls and guides.

Primetals Technologies will also supply HMI hardware and system software, control desks, the basic (level 1) automation, as well as motors and drives for the rolling mill. In addition, Primetals Technologies will deliver services for erection, commissioning and training.

Government Measures Disturb International Stainless Steel Trade

The global flow of stainless steel products has been negatively affected by the introduction of new trade barriers, in recent years. MEPS predicts that more disruption is possible.

Section 232 Quotas and Tariffs

The imposition of antidumping duties, by the US authorities, severely reduced shipments of stainless steel sheets and coils from China. Subsequently, Section 232 quotas and tariffs restricted imports from many other countries – notably, those in the Far East.

These actions were, clearly, intended to reduce the volume of purchases from overseas suppliers, and create opportunities for US steelmakers to increase their sales, expand production and employ more people. In fact, the major outcome has been price inflation in the domestic stainless steel market, raising costs for US customers. Furthermore, many imported products remain competitive, even after the application of duties or tariffs.

Local market observers believed that the Section 232 measures would be removed, in the short-to-medium term, following the achievement of various trade-related goals, by the US government. This prospect, however, is receding and the controls are likely to remain in place for the foreseeable future.

European Commission Safeguarding Measures

The European Commission reacted with safeguarding measures, to prevent third country tonnages, previously intended for the US market, from being diverted to the EU. Quotas were introduced, for individual products, for an initial 200-day period, based on recent average import tonnages. Recent figures show that, at the current rate, shipments of several products, including stainless steel bars and wire rod, are likely to exceed the quotas, and, consequently, incur tariffs. Purchasing behaviour is being adapted, accordingly.

Further uncertainty stems from the United Kingdom’s exit from the European Union. The “divorce” agreement, negotiated by the UK government and the EU, has yet to be accepted by the British parliament. Businesses must explore contingency plans.
